In this realm, there is a mighty tree of Life. Unfortunately, the monsters and beasts of the land are intent on destroying this tree of life. You are tasked with the job of defeating all of the enemies who come your way. Use your mouse to place archers and rifle men along the path. Destroy all the beasts before they can walk the path to the tree of life and cause it damage. As you place more defenders, upgrade the number of defenders you can place, and then upgrade the units in order to cause more damage. Keep fighting as you hold strong against the increasingly difficult waves.
